Task is running when there is no checksum stored, but status command returns 0

[maciej-lech]

Description

According to the docs for status schema reference:

A list of commands to check if this task should run. The task is skipped otherwise. This overrides method, sources and generates.

"This overrides method, sources and generates." indicates that source has more power over checksum/timestamp local state which make sense as it would handle the situation that you would like to check the state on a remote machine. (see example Taskfile)

Now, if the .task/checksum/buid is missing it executes the task always, despite the return code which doesn't make any sense and it is not what the documentation says.

Hello !

It looks like the schema reference is not up to date. Status can be combined with the fingerprint mechanism.
You can find the relevant documentation here.
For example:

version: '3'

tasks:
  build:prod:
    desc: Build for production usage.
    cmds:
      - composer install
    # Run this task if source files changes.
    sources:
      - composer.json
      - composer.lock
    generates:
      - ./vendor/composer/installed.json
      - ./vendor/autoload.php
    # But also run the task if the last build was not a production build.
    status:
      - grep -q '"dev": false' ./vendor/composer/installed.json

I'll update the schema reference!

I really don't understand that design change! Could you instruct me how can I write my Taskfile.yml (see example that I posted), so if I work in a team of 10ppl, if one has already built a docker image, those 9 left will not waste time to rebuild it? In the same time I need {{.CHECKSUM}} in status as it is part of the docker tag.

Thank you
